I believe investors should invest for the long run, so I don't buy and sell. I usually maintain the classic index of global equities, diversified U.S. and global and emerging markets, and when the risk is larger, I diminish the amount in global equities and put more into liquid assets - but very irregularly.

I am just a normal human being - I am alive! Why is anyone surprised that I am human? Like many New Yorkers, I have a multifaceted life.

I think globalization actually maintains and fosters various elements of national and cultural identities. I don't think everything is being homogenized. If anything, your food, your culture, and your ethnicity might become part of the globalized world, and thus absorbed by other countries.

What we need to understand is, one, that there are market failures; and two, that there are things like asset bubbles and irrational exuberance. There are periods of booms, bubbles, and manias. These things, if left to themselves, can lead to crashes, to busts, to panics.

In the history of modern capitalism, crises are the norm, not the exception.

I believe in market economics. But to paraphrase Churchill - who said this about democracy and political regimes - a market economy might be the worst economic regime available, apart from the alternatives. I believe that people react to incentives, that incentives matter, and that prices reflect the way things should be allocated. But I also believe that market economies sometimes have market failures, and when these occur, there's a role for prudential - not excessive - regulation of the financial system.

The global financial crisis - missed by most analysts - shows that most forecasters are poor at pricing in economic/financial risks, let alone geopolitical ones.
